Control unit for DSP and audio signal distribution to active external loudspeakers
 Šerík, Martin ; Ing. Jiří Stifter, Ph.D., FEL ZČU v Plzni (referee) ; Kratochvíl, Tomáš (advisor)
The paper deals with analysis of the problems of digital signal processing and with design of the control unit for DSP and audio signal distribution to active external loudspeakers. It describes function of delta-sigma AD converters, the most widely used digital filters and Fast Fourier Transform. The processed signal will be send to external loudspeakers using an Ethernet interface. The paper also covers the design of signal processing unit's hardware and software. Achieved functions and parameters of the unit are discussed in conclusion.

Active loudspeaker with digital audio signal input and additional functions
 Nedoma, Jakub ; Ing. Jiří Stifter, Ph.D., FEL ZČU v Plzni (referee) ; Kratochvíl, Tomáš (advisor)
The aim of the diploma thesis was to design active loudspeakers. The project contains the final solution of the designed loudspeakers that have a digital input of the multichannel audio signal with both sided data communication. In the work, there are also created circuits for processing an audio signal with a following amplification for the loudspeakers. Added functions are an infra acceptor for a remote control and binary outputs for assistant functions - a control of the motor and an indication via LED diodes.

System for monitoring and setup of signal processor in digital loudspeaker system
 Laník, Jakub ; Ing. Jiří Stifter, Ph.D., FEL ZČU v Plzni (referee) ; Kratochvíl, Tomáš (advisor)
This project solves teoretical design of digital reproductor system and controlling GUI software. This digital system is composed of one master unit, which digitalize different audio sources and stream them by ethernet to slave units. The controlling software is be able to set and monitor the audio system.
